Abstract
Deep-inelastic ep scattering data, taken with the H1 detector at HERA, are used to study the event shape variables thrust, jet broadening, jet mass, C parameter and two kinds of differential two-jet rate. The data cover a lar ge range of the four-momentum transfer Q, which is considered to be the rel evant energy scale, between 7GeV and 100 GeV. The Q dependences of the mean values are compared with second order calculations of perturbative QCD app lying power law corrections proportional to 1/Q(p) to account for hadroniza tion effects. The concept of power corrections is investigated by fitting s imultaneously a non-perturbative parameter <(alpha)over bar>(p-1) and the s trong coupling constant a,.
